Knative Eventing channels

Channels are Kubernetes Custom Resources that define a single event forwarding
and persistence layer in Knative. Messaging implementations provide
implementations of Channels via the
ClusterChannelProvisioner
object, and support different technologies, such as Apache Kafka or NATS
Streaming.

Note: Cluster Channel Provisioner (CCP) has been deprecated and will be
unsupported in v0.9. You should now use the Channels CRDs.
